C Programs to print Half start Pyramid

C-Pattern-Programs

In this article, we are going to learn how to print a half Pyramid using the C language. We will try to use two different techniques to print this pattern.

  1. Using normal for loop to print Pyramid pattern.
  2. Using decrement Operator in for loop to print Pyramid pattern.
  3. Using normal for loop to print Pyramid pattern.

In this example, we will use a simple for loop to print the half Pyramid.

1. C Programs to print Half start Pyramid

In this c program we are using the for loop to print a half pyramid pattern in C

#include<stdio.h>
int main()
{

  int num;

  printf("Please enter the size for Pyramid: ");
  scanf("%d",&num);

  for(int row=1;row<=num;row++)
  {
    for(int col=1;col<=row;col++)
    {
      printf("* ");
    }

    printf("\n");
  }

  return 0;
}

Actual Output:

Please enter the size for Pyramid: 5
* 
* * 
* * * 
* * * * 
* * * * *

2. C Programs to print Half start Pyramid decrement operator

In this example, we are using the for loop with a decrement operator for the Pyramid pattern print.

#include<stdio.h>
int main()
{
  int num;

  printf("Please enter the size for Pyramid: ");
  scanf("%d",&num);

  for(int i=num; i>=1; i--)
  {
    for(int j=i;j<=num;j++)
    {
      printf("* ");
    }
    printf("\n");
  }

  return 0;
}

Output:

Please enter the size for Pyramid: 5
* 
* * 
* * * 
* * * * 
* * * * *

3. C Programs to print Half start Pyramid using Nested loop

In this example, we are using the for loop with a decrement operator in the inner for loop to print the Pyramid pattern.

#include<stdio.h>
int main()
{
  for(int i=1;i<=5;i++)
  {
     for(int j=i;j>=1;j--)
     {
       printf("* ");
     }

     printf("\n");
  }
  return 0;
}

Output:

Please enter the size for Pyramid: 5
